The Calgary Herald has an article about how people are scaming QR code users or attack tagging or "attaging".  Wher people are placing stickers on company's posters where it is very hard to be able to detect that these stickers have been placed over top of the original. These sticker when people scan them with their smart phones it will send them to a fake website which usually have a trojan linked to them and the website looks very similar to the actual company's website.
